Answer: Two types of salt are sea salt and iodized salt. I know more types, but you only asked for two types of salt.
Explanation:
Answer:
Sea salt: Sea Salt also called bay salt or solar salt is a white salt produced from the evaporation of seawater, rather than by being extracted from sedimentary deposits. It is popularly used in cooking and cosmetics.
Himalayan salt: Of the different types of salt, Himalayan salt is the purest form of salt in the world and is harvested by hand from Khewra Salt Mine in the Himalayan Mountains of Pakistan. Its color ranges from off-white to deep pink. The salt is rich in minerals – it contains the 84 natural minerals and elements found in the human body. Himalayan salt is used in spa treatments, as well as the kitchen.

what structure is sometimes considered a type of volcano.
Answer:
Some of the Earth's grandest mountains are composite volcanoes--sometimes called stratovolcanoes. They are typically steep-sided, symmetrical cones of large dimension built of alternating layers of lava flows, volcanic ash, cinders, blocks, and bombs and may rise as much as 8,000 feet above their bases.

The number of atoms in the 0.940 grams P₂O₅ is equal to 3.4 × 10²¹ atoms.
What is Avogadro's number?Avogadro’s number is the number of particles in one mole of any substance or element. Generally, these entities can be atoms, molecules, ions, protons, or electrons, depending upon the kind of chemical reaction or reactant and product.
The Avogadro’s constant is experimentally found approximately equal to 6.022 × 10²³ mol⁻¹.
Given, the amount of phosphorous oxide, P₂O₅ = 0.940 g
The molecular mass of the phosphorous oxide, P₂O₅ = 141.95 g/mol
It means that 141.95 g of P₂O₅ contains atoms = 6.022 × 10²³
Then 0.940 g of P₂O₅ will contain atoms = (0.940/141.95) × 6.022 × 10²³
= 0.034 × 10²³ atoms
= 3.4 × 10²¹ atoms
Therefore, the atoms in the 0.940 grams P₂O₅ are 3.4 × 10²¹ atoms.

Answer:
30.942 g of NaCl
Explanation:
The balance chemical equation is
CuCl₂ + 2 NaNO₃ → Cu(NO₃)₂ + 2 NaCl
Calculate moles of CuCl₂
Moles = 37 g / 134.45 g/mol = 0.275 mol
Calculate moles of NaNO₃
Moles = 45 g / 84.99 g/mol = 0.529 mol
According to balanced chemical equation the mole ratio of CuCl₂ : NaNO₃ is 1 : 2.
Hence,
0.275 : 0.550 or 0.529 : 0.264
This means that the NaNO₃ is the limiting reagent.
Now mole ratio of NaNO₃ and NaCl is 2 : 2 or 1 : 1.
Hence, 0.529 mol of NaNO₃ will produce 0.529 mol of NaCl.
Now,
Mass = Moles x M.Mass
Mass = 0.529 mol x 58.44 g/mol
Mass = 30.942 g of NaCl

g What is the molality of a solution produced using 15.2 g of Calcium chloride and 345 g of methanol (CH3OH)
Considering the definition of molality, the molality of a solution produced using 15.2 g of calcium chloride and 345 g of methanol is 0.397 [tex]\frac{moles}{Kg}[/tex].
MolalityMolality is a measure of the number of moles of solute in a solution corresponding to 1 kg or 1000 g of solvent.
This is, molality is the ratio of the number of moles of any dissolved solute to kilograms of solvent:
The Molality of a solution is determined by the expression:
[tex]Molality= \frac{number of moles of solute}{kilograms of solvent}[/tex]
Molality is expressed in units [tex]\frac{moles}{Kg}[/tex].
Solute and solventThe solution is a homogeneous mixture of two or more components that have the same chemical and physical properties in a single phase. A solution is made up of two main components: the solute and the solvent.
That is, the solute and the solvent are the components of a chemical solution, that is, of a homogeneous mixture that occurs when one or more substances are dissolved in another substance.
The solute is the substance that dissolves in a solution. In solution, the solute is usually found in a lower proportion than the solvent.
Solvent, also known as solvent, is the substance in which a solute dissolves, resulting in a chemical solution. Generally, the solvent is the component that is found in the highest proportion in the solution. It will always be the solvent who will determine the state of the matter that will have the solution.
This caseIn this case, since calcium chloride is found in a smaller proportion and methanol in a greater proportion, calcium chloride is the solute and methanol is the solvent.
Being the molar mass of calcium chloride 110.98 g/mol, the number of moles of the compound contained in 15.2 g is calculated by:
[tex]15.2 gramsx\frac{1 mole}{110.98grams}[/tex]= 0.137 moles of calcium chloride
On the other side, you have 345 g of methanol. This is, you have 0.345 kg of methanol (being 1000 g= 1 kg).
Then, considering the solute and solvent, the molality can be calculated as:
[tex]Molality= \frac{0.137 moles}{0.345 kg}[/tex]
Solving:
Molality= 0.397 [tex]\frac{moles}{Kg}[/tex]
Finally, the molality of a solution produced using 15.2 g of calcium chloride and 345 g of methanol is 0.397 [tex]\frac{moles}{Kg}[/tex].

What is the final temperature of the water mixture if no heat is lost? The specific heat of water is 4.18 J g⋅ ∘C, the specific heat of steam is 2.01 J g⋅ ∘C, and Δvap=40.7 kJ/mol.
The final temperature of the water is 75.6∘C.
What is condensation?Condensation is the process by which steam is converted to water at the boiling point of water. Heat lost by steam = Heat gained by water.
Heat lost by steam= ( 0.534 g × 2.03 × (104 - 100)) + (0.534 g × 40.7 × 10^3 / 18) = 4.34 + 1207.4 = 1211.74 J
Heat gained by water = ( 4.86 × 4.18 × (T2 - 15.9 ∘C))
1211.74 = 20.3T2 - 322.77
1211.74 + 322.77 = 20.3T2

A baby weighs 7 pounds, 1 ounces at birth and 6 pounds, 12 ounce at discharge. What percent of weight did the baby lose?
Round your answer to the nearest whole number.
Answer:
5%
Explanation:
6 lbs and 12 ounces is 6.75 lbs.
7 lbs and 1 ounce is 7.0625 lbs.
6.75 divided into 7.0625 is about 0.95, or 95%. The baby has kept 95% of its weight.
100% minus 95% is 5%, this is how much the baby lost.

The bond energy between carbon and oxygen is 358 for a single bond (C–O) and 745 for a double bond (C=O). Why is the bond energy higher for double-bonded carbon and oxygen (C=O)?
A. Additional bonds require less energy to break, so the bond energy is higher.
B. Additional electrons attract each other, decreasing the distance between atoms, and increasing bond energy.
C. Additional electrons repel each other, increasing the distance between atoms, and increasing bond energy.
D. Additional bonds require more energy to break, so the bond energy is higher.
This problem is providing the bond energy for the bonds C-O and C=O which are 358 and 745 respectively, so that a feasible explanation to this behavior is required. At the end, one concludes the correct answer is C. "additional electrons repel each other, increasing the distance between atoms, and increasing bond energy" according to the following:
Bond energy:In chemistry, we study the bond energy as the energy required to break the bond, binding two elements. In such a way, we can evidence that the more bonds between the atoms, the higher the bond energy such as in the case of C-O and C=O.
In such a way, since bonds are formed between valence electrons, we see that the more of these an atom has available for bonding, the farther away they will be, as they are repelled; thus, causing more distance between atoms and making the bond to be longer.
Hence, the greater the distance between two atoms in a bond, the higher the bond energy; that's why the answer to this question is C. Additional electrons repel each other, increasing the distance between atoms, and increasing bond energy.

How many grams are there in 5.0 L of chlorine gas at STP?
Answer:
1nmole of any ideal gas occupies 22.72 L
15.85 grams
Explanation:
Here we want to get the number of grams present in 5 litres of chlorine gas at STP
At STP, 1 mole of gas occupies a volume 22.4 dm³
X moles will occupy 5L (litres)
Thus we have that :-
[tex]x \times 22.4 = 5 \times 1[/tex]
[tex]→x = \frac{5}{22.4} [/tex]
[tex]→x = 0.2232 \: moles[/tex]
Mathematically, the number of grams is the product of the number of moles and molar mass.
Molar mass of chlorine gas is 71 g/mol
So,
Mass = Mole × Molar mass
→ 0.2232 × 71
→ 15.85 g
